After an election, new trustees are often overwhelmed by a very steep learning curve. There's orientation sessions, preparation for Board meetings, Results Review meetings with school Principals and central service administrators, a planning retreat, and on it goes. And all of this would be on top of any regular job and family commitments that you're already trying to manage.
As busy as it gets, though, do make the effort to keep in touch with the people of your ward who have placed their trust in you. Try to attend as many school events as you can. There's usually some kind of meet the teacher function at the beginning of the school year, and a slew of events throughout the year, from Read-In Week, to awards nights, to grads. If you let your school communities know you're interested, you'll get plenty of invitations.
And make use of the new technologies- host a website or a blog. Use Facebook or Twitter. Not only will these communication vehicles keep your constituents informed of initiatives that you and the Board are involved in, they help people feel that they made a good decision placing their trust in you at the ballot box and it's a great way to develop your support base for the next election.
